For measurement of local conductivity and temperature in
multiphase
flows with gaseous and liquid compartments
in pipes, columns and reactors.
From this e.g. the following parameters can be derived:
- averaged local void fractions and bubble count
- phase temperature
- velocities of the gaseous phase (double-tip probe)
